  • Dependency libz-rs-sys ^0.5.1 is slightly outdated

    Consider upgrading to 0.6.6 to get all the fixes and improvements.

    In Cargo, different 0.x versions are considered incompatible, so this is a semver-major upgrade.

  • Missing categories

    Categories improve browsing of lib.rs and crates.io. Add categories = ["development-tools::build-utils"] to the Cargo.toml.

    Even if there are no categories that fit precisely, pick one that is least bad. You can also propose new categories in crates.io issue tracker.

  • Missing keywords

    Help users find your crates. Add keywords = ["untrusted", "font", "build", "ots", "sanitiser"] (up to 5) to the Cargo.toml. Best keywords are alternative terms or their spellings that aren't in the name or description. Also add a keyword that precisely categorizes this crate and groups it with other similar crates.

  • Using outdated edition for no reason

    We estimate that this crate requires at least Rust 1.63, which is newer than the last 2015-edition compiler. You can upgrade without breaking any compatibility. Run cargo fix --edition and update edition="…" in Cargo.toml.

    Using the latest edition helps avoid old quirks of the compiler, and ensures Rust code has consistent syntax and behavior across all projects.

    The Edition Guide

• core-graphics-types

  • Imprecise dependency requirement bitflags = ^2

    Cargo does not always pick latest versions of dependencies! If Cargo.lock ends up having an unexpectedly old version of the dependency, you might get a dependency that lacks features/APIs or important bugfixes that you depend on. This is most likely to happen when using the minimal-versions flag, used by users of old Rust versions.

    If you want to keep using truly minimal dependency requirements, please make sure you test them in CI with -Z minimal-versions Cargo option, because it's very easy to accidentally use a feature added in a later version.

  • Missing keywords

    Help users find your crates. Add keywords = ["bindings", "macos", "core-graphics", "core-foundation", "complete"] (up to 5) to the Cargo.toml. Best keywords are alternative terms or their spellings that aren't in the name or description. Also add a keyword that precisely categorizes this crate and groups it with other similar crates.

  • No readme property

    Specify path to a README file for the project, so that information about is included in the crates.io tarball.

• mozjs_sys

  • Could not fetch repository

    We've had trouble cloning git repo from https://github\.com/servo/mozjs\.git

    At the moment we only support git, and attempt fetching when we index a new release. Cloning is necessary for lib.rs to gather data that is missing on crates.io, e.g. to correctly resolve relative URLs in README files, which depend on repository layout and non-standard URL schemes of repository hosts.

  • Locked dependency version icu_capi =1.5.0

    This can easily cause a dependency resolution conflict. If you must work around a semver-breaking dependency that can't be yanked, use a range of versions or fork it.

    icu_capi versions

  • No readme property

    Specify path to a README file for the project, so that information about is included in the crates.io tarball.

  • Big download

    The crate is a 33MB download. You can use cargo package command to review crate's archive in target/package dir.

    Check that large files weren't included by accident. Note that tarballs uploaded to crates.io can't be used to run examples or tests, so it's fine to exclude them and their data files. You can use the include or exclude properties in Cargo.toml to minimize crate's download size. Crates.io keeps all versions of all crates forever, so this storage adds up.

  • Dependency icu_capi =1.5.0 is outdated

    Upgrade to 2.2.0 to get all the fixes, and avoid causing duplicate dependencies in projects.

    Easy way to bump dependencies: cargo install cargo-edit; cargo upgrade -i; Also check out Dependabot service on GitHub.

    icu_capi versions

  • Dependency libz-rs-sys ^0.5.1 is slightly outdated

    Consider upgrading to 0.6.6 to get all the fixes and improvements.

    libz-rs-sys versions

  • Imprecise dependency requirement cc = ^1

    Cargo does not always pick latest versions of dependencies! Specify the version as cc = "1.4.0". If Cargo.lock ends up having an unexpectedly old version of the dependency, you might get a dependency that lacks features/APIs or important bugfixes that you depend on. This is most likely to happen when using the minimal-versions flag, used by users of old Rust versions.

  • Latest stable release is old

    It's been over 6 years. Is this crate still maintained? Make a new release, either to refresh it, or to set

    [badges.maintenance]
    status = "deprecated"
    

    (or "as-is", "passively-maintained").

    Users pay attention to the latest release date. Even if the crate is perfectly fine as-is, users may not know that.

Best keywords are alternative terms or their spellings that aren't in the name or description. Also add a keyword that precisely categorizes this crate and groups it with other similar crates.

  • Published crate contains binary files

    The crate contains binary files (DOS exe, Mach-o exe, Python package, autotools obfuscated code, obscure autoconf code). Crates are meant to be compiled from source. Please check that you haven't published temporary build files by accident. If you have test fixtures, consider excluding them from crates-io tarball, since Cargo doesn't run tests from crates-io packages.

    Audit page

  • docs.rs build failed

    docs.rs site failed to build the crate, so users will have trouble finding the documentation. Docs.rs supports multiple platforms and custom configurations, so you can make the build work even if normal crate usage has special requirements.

    Docs.rs doesn't need to run or even link any code, so system dependencies can simply be skipped. You can also set cfg() flags just for docs.rs and use them to hide problematic code.

  • The Cargo package has no git commit information

    Before publishing a package, make sure all packaged files are committed to the repository, and there are no "dirty" files. Push this commit to crate's public repository.

    To protect against supply chain attacks similar to CVE-2024-3094, lib.rs will soon start flagging non-reproducible packages without public source code as suspicious. Currently only git repositories are supported (but may be hosted anywhere, not just GitHub). If you'd like a different SCM supported, please file a feature request.
